Inspecția tehnică periodică începe la stația ITP.

Because Romanian usually puts the definite article at the end of the noun, not as a separate word like English the.

• inspecție = inspection
• inspecția = the inspection

So Inspecția tehnică periodică means the periodic technical inspection.

For many feminine singular nouns ending in -ie, the definite form ends in -ia.

In Romanian, adjectives usually come after the noun.

So:

• inspecție tehnică = technical inspection
• inspecție tehnică periodică = periodic technical inspection

This is the normal, neutral word order. Romanian can sometimes place an adjective before the noun, but that often sounds more literary, emphatic, or stylistically marked. In this sentence, the post-noun position is the standard choice.

Because adjectives in Romanian agree with the noun in gender and number.

Here the noun is:

• inspecția — feminine singular

So the adjectives must also be feminine singular:

• tehnic → tehnică
• periodic → periodică

That agreement is why all three words match:

• inspecția (feminine singular definite noun)
• tehnică (feminine singular adjective)
• periodică (feminine singular adjective)

Because Romanian handles definiteness differently from English.

English says:

• the periodic technical inspection

Romanian says:

• inspecția tehnică periodică

The the meaning is already built into inspecția. The adjectives do not need their own article here. Once the noun is definite, the whole noun phrase is understood as definite.

Începe is the 3rd person singular present tense of the verb a începe, meaning to begin or to start.

So:

• eu încep = I begin
• tu începi = you begin
• el/ea începe = he/she/it begins

In this sentence, the subject is Inspecția tehnică periodică, which is singular, so the verb must also be singular:

• Inspecția ... începe = The inspection begins

Romanian often leaves out subject pronouns when they are not needed.

The verb form începe already shows that the subject is 3rd person singular, and the noun phrase Inspecția tehnică periodică is explicitly there anyway. So adding ea would be unnecessary.

Romanian does this much more often than English.

Here la means at.

The verb a începe can be followed by a place introduced with la when you want to say where something begins or starts.

So:

• începe la stația ITP = begins at the ITP station

This is a very natural way to express location in Romanian.

For the same reason as inspecția: stația is the definite form.

• stație = station
• stația = the station

In stația ITP, the noun is being made specific: it is not just any station, but the ITP station/testing station. Romanian often uses the definite form when the noun is clearly identified by context or by a following label like ITP.

If you said la o stație ITP, that would mean at an ITP station / at one ITP station.

ITP stands for Inspecția Tehnică Periodică.

So the sentence first gives the full expression and then uses the common abbreviation:

• Inspecția tehnică periodică ... la stația ITP

This is very common in Romanian: first the full term, then the acronym.

The given order is the most neutral and natural one:

• Inspecția tehnică periodică — subject
• începe — verb
• la stația ITP — place

Romanian word order is somewhat flexible, but changing it usually changes emphasis.

For example:

• La stația ITP începe inspecția tehnică periodică.

This is still grammatical, but now the location is emphasized more strongly. The original sentence is the straightforward, standard version.

The main ones here are:

• ț in inspecția, stația
  Pronounced like ts in cats

• ă in tehnică, periodică
  A short central vowel, somewhat like the weak vowel in the second syllable of sofa, but not exactly the same

• î in începe
  A close central vowel that does not exist in standard English; learners usually need practice with it

A rough pronunciation guide for the whole sentence would be something like:

• in-SPEK-tsi-a TEH-ni-kuh pe-ri-O-di-kuh in-CHE-pe la STA-tsi-a I-T-P

That is only approximate, but it can help as a first step.
